Two masses are suspended from a pulley as shown below. 4.0 kg | 3.0 kg 0.60 m They are released and made to move vertically. Because of the friction at the pulley, the speeds of the two masses are constant throughout their motion. The 4.0 kg mass moves 0.60 m before hitting the ground. What is the amount of heat generated at the pulley? 5.9 J 18J O 241 41J
